...He said, "You can unmute the TV now."
Double the normal volume.
So loud it was deafening.
And he couldn't hear it.
So up to 86, and that's where we had to bear with it. Basically four times normal volume. (Volume does not increase linearly.) That...was rather the experience.
He went to bed midway through, and instantly, we dropped the volume down to the normal level, where we'd be fine. Suffice to say: my grandfather is basically as close to deaf as you can be without being deaf. He mishears things all the time, and is a royal pain to work with.
Unfortunately, it is very much genetic. My dad is 66. (My grandfather is in his 90s. I forget how old exactly.) He...has the exact same problem. And the trigger for my misophonia that my dad does when he eats...well, that's genetic too. Because my grandfather is actually worse, making that noise all. the. time. Like, basically every couple of minutes, he'll...I'm not sure how to explain it, other than "smack his lips", and it makes that noise. The one, and as far as I know, ONLY noise which triggers the misophonia.
I'm not looking forward to being that way when I age, though unlike both of them, at least I'd admit I'd need a hearing aid. I mean, sure. I wouldn't notice at first. It'd have to be pointed out to me. But when it was, I'd instantly at least consult with a doctor, to see about how bad it is and when I'd need to treat it. Fear of losing said hearing aid is ridiculous, so I wouldn't let that stop me.
Basically, there are a lot of genetics very strong in our family, unfortunately. And whether they're nature or nurture, you can find a bunch in me even now. A defining trait, basically the defining trait, of both my grandfather and my father, is stubbornness. Did you know you could inherit stubbornness? I know I did, and anyone who has interacted with me knows that much! (Especially in mafia games.)
There's a bunch of other stuff, too. Like, the same hesitations in speech, the low speaking tone, face being basically a permanent frown unless it's laughing and/or smiling (basically, a default "guard face" as it'd be diplomatically called in my profession), lots of stuff for better or worse.
Suffice to say there's a lot of reasons I hate what I've inherited. One generation perfectly mimicking and following the habits of the previous. My dad is basically worse than my grandfather was fifteen years ago. (My grandfather managed to, for the longest time, stay in better shape than my dad did, so my dad's accelerated decay is probably because he's not in as good of shape as my grandfather was at his age.)
I won't inherit some problems--I will always watch my weight to make sure I don't suddenly gain 30 pounds, for instance. But to be fully honest, the opposite is what I'm more concerned about. (I'm 6'2" and weigh 137.5 as of a couple days ago: healthy enough, and within my 140 +/- 10 range. On the lower end of things and technically underweight, but not dangerously so. My critical zones as I define them are below 130 and above 152. If I reach either, I'm in need of a serious change in lifestyle.)
But even if I have transitioned, biology is a very strong factor, so it's something I'll be forced to live with later in life. Of course, that's a cross-bridge-come-to-it thing. Even if my health decays, the earliest I could possibly show symptoms would be ten to fifteen years from now, late thirties to early forties.
It will happen eventually though.
Hopefully by then I'll be in a much better position than I am now.
